Step 4:
8 goes into 33 4 times with a remainder of 1.
Write down 4 as next digit of of the result. 
Result so far: 254
Subtract 32 from 33 to get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 8

Step 5:
8 goes into 10 1 times with a remainder of 2.
Write down 1 as next digit of of the result. 
Result so far: 2541
Subtract 8 from 10 to get 2.

The final result is 2541 with a remainder of 2.
